Also note that the addition of a business track does not seem to materially change the # of people. I think it would be nice to have an additional track -- and maybe we could use that room for vendor presentations? I would just be afraid of charging a vendor $x to give a presentation and then only three (or none) of our members go to the separate room.
So the idea above - still have two rooms but maybe not worry if we cannot completely fill two rooms full of sessions as we could put a vendor in there doing a presentation if we did not have a business track presentation to fill that slot.
